Application filed February 4, 1922. Serial No. 534,234.

To aZZw/tomt'tmay conce/m.'

Be it hereby known that l, Winnni'aiu Tn'oitrsoN, a citizen ot' the United States,`

and a resident et Portland, in the county ot' .ildultnomah and State ot Oregon, have invented a new and useitul rfire Guard, ol which the tollowing a specification.

This invention relates more particularly to pneumatic tires.

The objects of my invention are to provide an exceedingly simple and etlicient attachment for pneumatic tires which will protect the tire, reintorce it in weak places, `give it better traction and reduce skidding. l iitnother object is to reduce the liability et punctures.

A tui-ther object is to so construct same that the various units may be separated at different distances if desired, and at the `same time enable one to replace any single section without removing the others.

A still further object is the utilization oi the goed port-ions of defective tires in the protection of other tires.

l accomplish these results in the manner set fort-h in the following' specilication and illustrated in the accompanyingl drawing, in which:

Figure 1 illustrates a section ot a tire a part otl which is equipped with my device and also a section through one of the units trom which the tire has been removed. Figure E2 is a section through the device between units and shows its relation to a tire and rim. Figure 23 is a section through 3MB in AFig. 1. VFigure 4 is a perspective oi one oi the clamps. l `igure 5 a view ol the clamps from the inside et the device. Fign ure a plan olE the clamp ot which Fig'- ure 7 is an elevation.

Similar numbers of reference refer to the same or similar parts throughout the several views.

Referring in detail to the drawing7 I have illustrated a rim 10on which the usual outer casing 11 is attached. This may be either clincher or straight side.

Referring more particularly to my device it will be seen that 1 have utilized a plurality of tire sections 12 which 1 have placed over the tire, leaving spaces 13 between same. On each side of these sections in the groove or bend which ordinarily engages the wheel rim 10 l have placed a wire ring 14 whose ends 15 are foruied into eyes through which 1s passed a bolt 1G for adjusting purposes. Between the casing 11 and the ends of the section 12 .l have placed the wires .17 whose.`

ends 18 bend outwardly through the spaces 13. (lne end 18 passes below the wire 14 and bends upwardly around same and the other end 18 passes over the wire 14 and bends downwardly around same. In other words7 the clamping` wire 17 has right and left ends which naturally workin conjunction with adjacent cla1nps17.

ln Figure 5 I have somewhat exaggerated the relation of the clamps 17 in order to show the manner in which they hold the various sections 12 against the wire 14. It will be evident that the ends 18 can be bent in the saine direction, in which case both ends et one clamp 17 would pass around the top ot the wire 14 and both ends ot' the adjacent clamp 1'? would pass around the bottom of the wire 14.

It will be also observed that I have illustrated the adjacent clamps as overlapping or hooking into one another. This also can be dispensed with incertain cases, inasmuch as the strain oli' holding the various sections 12 in place upon the casing 11 `must be taken care of by the wires 14, which, it will be seen, must be relatively strong, whereas the clamping wire 17 can be Yfairly light as they have only a small proportion of the load to carry; but they should be made from some ductile material in order to facilitate their application or removal.

lt will be understood that in the practical application ot this device it is desirable to utilize sections 153 cut lrom a tire or outer casing similar in size to the casingl 11, although this is not absolutely necessary.

l'n driving over muddy or wet roadways greatly increased traction is secured and the tendency to puncture is greatly reduced, since the object which would ordinarily cause a puncture must either pierce through the extra thickness of the member 12 or be robbed of an equal amount ot length in case it should attempt to pass through the casing 11 at one of the spaces 13, in which event it is more liable to be deflected by the casing itseltI on .account of the space between the casing and the roadway.

ln applying this device to a tire having` one or more weak spots it can be s-o arranged that the sections l2 will cover these Weak places7 thereby reinforcing saine greatly and adding to the length of life of a tire.

I am aware that numerous devices have been constructed purporting to utilize sections of worn tires for a similar purpose. I therefore do not claiin iny invention broadly but only Within the limits setI 'forth in the following' elaini.

l/Vhat l claiin is:

A protective armor 'for pneumatic tires consisting of a plurality of divided tire sections, in combination with a pair of closed rings adapted to lie against the outer sides of said tire sections above the beads of said sections when spaced around a tire and a plurality of clamp members adapl'ed lo hold Aach end olf each lire section in spaced relation and against ils Wire rings, each ol said clamps consistingl o`l` :i piece ol wire placed on the inside ol' a Jrire seel'ion behind said ring, the ends 0li said wire turningi oul- Wardly and hookingy over .said ring beyond the corresponding hook olz the adjacent clamp in a n'ianner thatV said adjacent4 hooks will overlap.` said hooks being.;l opened in a manner to permit the individual sections lio be renioved Wilhout movingr any ol'her portion of the armor except elle clamps lor that; section.
